There are circuits that provide a trickle of current to the memory, not the battery Lithium batteries like the one that is in the AN1x -- as opposed to the Lithium-ion batteries in laptops -- will EXPLODE if charged. (I've seen one go off in a lab: It tore the top of a PC off like a giant can opener!) However, there are additional complexities (design and safety) to providing current to the memory using an external power supply, so many manufacturers don't bother. I have no idea how the AN1x is set up, so the safer assumption is that it doesn't provide this feature.
